How Do You Pay for BWI Long Term Parking Online?

BWI's on-airport Long Term Lots do not currently offer a direct official pre-payment portal through bwiairport.com. Instead, travelers use third-party booking platforms to pay online, secure a reservation, and skip the walk-up kiosk line entirely.

Here is a step-by-step walkthrough for how to BWI long term parking pay online:

1. Choose a platform. Visit Triply, SpotHero, or Airport Parking Reservations and enter your travel dates.
2. Compare lots. Filter by on-airport Long Term or nearby off-site alternatives. Prices display per day with totals for your full trip.
3. Enter your vehicle and payment details. Most platforms accept Visa, Mastercard, Amex, Discover, and mobile wallets like Apple Pay and Google Pay.
4. Receive your confirmation. You'll get an email or app confirmation with your booking code and lot entry instructions.
5. Arrive and present your booking. At the lot, scan your QR code or enter your booking number. No need to stop at a kiosk on exit.

If you arrive without a reservation, walk-up payment is still accepted at exit kiosks in both Long Term Lots A and B. The kiosks accept cash, Visa, Mastercard, Amex, Discover, and contactless payment, according to BWI's official parking page. You simply take a ticket on entry and pay when you leave.

These rates took effect July 1, 2024 — the first price adjustment since 2009. For a 7-night trip, Long Term Parking saves you $35 vs. the Daily Garage and $133 vs. the Hourly Garage, based on official MAA published rates.

Where Are BWI Long Term Parking Lots A and B Located?

Both Long Term Lots are located on the south side of the airport campus, accessible from Interstate 195 (the primary airport access road) and MD Route 170 (Aviation Boulevard). Signage from I-195 directs you to the lots before you reach the main terminal loop.

Lot A is the first lot you'll reach coming from the main airport entrance. Lot B sits adjacent to Lot A, slightly farther from the terminal. Both lots are open-air and served by the same free shuttle circuit. Before you drive, check real-time traffic on Waze — traffic on I-195 from I-95 can back up during rush hour, especially on Friday afternoons.

For a deeper look at Lot A's layout and space types, see our guide to BWI Long Term Parking A.

How Does the BWI Long Term Parking Shuttle Work?

The free shuttle from BWI Long Term Lots A and B runs every 10-15 minutes to the terminal, 24 hours a day. Between 1–5 AM, frequency drops to every 25 minutes. The shuttle is operated by BWI Marshall Airport under the Maryland Aviation Administration.

Key things to know about the shuttle:

• Pick-up points are marked at covered shelter stops throughout both lots.
• The shuttle drops you at the lower level of the terminal near the ticketing area.
• Allow at least 20-30 minutes from your car to the security checkpoint — more during peak travel periods.
• The same shuttle route also serves Express Parking and connects to the BWI Rail Station for MARC and Amtrak access.
• Shuttle service is completely free — no tip or fare required.

Is It Cheaper to Book BWI Long Term Parking in Advance Online?

Booking BWI long term parking online in advance can save you money compared to walk-up rates, especially through third-party platforms that offer promotional pricing. On-airport Long Term Lot rates are set by the MAA at $11/day, but third-party platforms occasionally list discounted bundles or coupon codes that reduce the total.

Beyond price, there are other strong reasons to book ahead:

• Guaranteed spot. BWI's on-airport facilities hold ~22,000 spaces total, but Long Term Lots can fill up during holidays and summer peak travel.
• Faster entry. Pre-paid bookings let you scan in and out without stopping at a kiosk.
• Free cancellation. Most third-party platforms offer free cancellation up to a few hours before your arrival — check terms at booking.
• Price lock. Booking early locks in the rate, which matters if demand pricing applies on the platform you use.

What Payment Methods Are Accepted at BWI Long Term Parking?

Walk-up payment at BWI Long Term Lot exit kiosks accepts cash, Visa, Mastercard, American Express, Discover, and contactless payment (including Apple Pay and Google Pay), according to BWI's official parking information. No single payment method is required — the kiosks are well-equipped for most travelers.

When booking online through third-party platforms, accepted payment methods typically include all major credit and debit cards plus digital wallets. Always confirm accepted methods at checkout, as individual platform policies vary slightly.

On-Site vs. Off-Site BWI Long Term Parking: Which Is the Better Deal?

Off-site lots near BWI are consistently cheaper than on-airport Long Term Parking. Based on our analysis of current rates, the best off-site options run $7.50–$10/day compared to the official on-airport rate of $11/day — a savings of up to 32%.

Off-site lots like FastPark 2 are only 2 minutes from the airport and offer covered parking — something BWI's Long Term Lots don't provide. All major off-site lots include free 24/7 shuttle service, free cancellation, and online booking. For a full breakdown of nearby alternatives, see our guide to airport parking near BWI.

On-airport Long Term Parking makes the most sense if you want to stay fully within the airport ecosystem, prefer a single payment at exit, or need ADA-accessible parking (accessible spaces are available in all on-airport garages and lots).

Tips for Saving Money on BWI Long Term Parking

A few smart moves can cut your BWI parking bill significantly. These tips are based on current rates and our analysis of available booking platforms (as of 2026).

• Book through a comparison platform. Sites like Triply let you compare on-airport and off-site rates side by side. Off-site lots start at $7.50/day — that's a $24.50 savings on a 7-day trip vs. on-airport Long Term rates.
• Check for coupon codes before booking. Third-party platforms regularly offer promo discounts on BWI parking. Our BWI long term parking coupon guide tracks current deals.
• Consider the Rail Station Garage. At $12/day, the BWI Rail Station Garage connects directly to MARC Penn Line and Amtrak — useful if someone is dropping a car and taking the train back.
• Plan around shuttle frequency. The Long Term shuttle runs every 10-15 minutes. Add 30 minutes to your departure timeline to account for the walk, wait, and ride to the terminal.
• Enroll in TSA PreCheck. It won't lower parking costs, but TSA PreCheck cuts security time significantly — which means you don't need to arrive as early, reducing your parking days by potentially half a day on short trips.
• Check flight status before leaving. A delayed flight means extra parking days. Check FlightAware or your airline's app before driving in.

BWI Marshall Airport completed its $520 million Concourse A/B Connector in January 2026 — the largest capital project in the airport's history. The new connector streamlines movement between Concourses A and B. Parking technology upgrades, including smart guidance systems, are also rolling out across the facility in 2026.
